4 Claims. (Cl. -129) This invention relates to a hammock stand assemblyand more particularly to the combination of a hammock and stand.

In the past no attempt has ever been made to utilize the hammock itselfas a part of the hammock stand. Thus, in the prior art, hammock standswere assembled as a stand in an upright position independent of thehammock and the hammock is merely fastened inside the stand. However,under the present invention the hammock in eifect becomes part of thestand when the stand is located in final supporting position.

The result of applicants construction is that the overall length of thestand can be shortened without shortening the length of the hammock.This means that the hammock stand assembly of the invention can belocated in places where the length required under previous constructionswould prevent the use of a hammock and stand. in addition to theadvantage of less space requirement the present invention provides ahammock stand assembly wherein the hammock can be utilized as a hammockin a slack position and substantially like a day bed in a taut position.Furthermore, the construction is of light weight tubular metal which canbe collapsed and readily transported.

In general, the invention has a frame of three parts comprising acentral base section, including two laterally spaced tubular membersfrom one end of which extends a somewhat U shaped upright section andfrom the other end of which extends the rest of the base also ofgenerally U-shape. Pivoted to the base is a somewhat U-shaped memberthat can be raised or pivoted to an upright position oppositelyangularly disposed to the first upright section above referred to. Whenthe pivoted section is in raised position a pair of chains or the likeconnected to the base tend to pull the pivoted section downwardly andare opposed by tension in the hammock itself which extends between theupper outer end of the fixed upright section and the upper outer end ofthe hinged or pivoted section. The tautness of the hammock depends onthe length of the chains and therefore on the distance between the upperouter end of the pivoted upright and its base.

Other objects and advantages of the invention will appear hereinafter inconnection with the following description of the drawing illustrating anembodiment of the invention.

In the drawing:

and showing a hook supporting the other end of the hammock.

The stand for the hammock 1 is of three sections having a central basesection formed of two laterally spaced tubes 2 and 3, an end section 4and a second end section provided with a base 5 and a member 6 which ispivoted to base 5.

The two tubes 2 and 3 of the base section are shown.

of larger cross-section than the other parts of the frame and one end 7of the tubes extends downwardly and in assembled position encloses thelesser cross-section ends 8 of the base 5 carrying member 6. Theopposite ends 9 of the tubes 2 and 3 extend upwardly and enclose theends 10 of the end section 4. The portion of the tubes adjacent ends 9rest on the support on which the stand is located and the tubes extendgenerally upwardly therefrom, until reaching the end sections 7, atwhich point the tubes extend downwardly. Thus, the assembled frame whenplaced on a supporting surface is arched or bowed upwardly to provide aspaced, stable, four-point contact with the supporting surface.

The end section 4 is of a generally U-shaped tubular construction andwhen assembled with tubes 2 and 3 as in Figs. 2 and 3 takes a generallyupright position substantially as shown.

The remainder of the base of the stand is provided by base 5 the ends 8of which fit within ends 7 of tubes 2 and 3 as described. Base 5 is alsotubular and of a generally U-shape. The outer portions of base 5 rest onthe support on which the stand is located and the legs of the baseextend generally upward to receive the downwardly extending ends 7 ofthe generally upwardly extending tubes 2 and 3. The base 5 and tubes 2and 3 thus provide the assembly with a springlike support.

The upright section corresponding to end section 4 ,and located oppositeto section 4 is provided by the generally U-shaped tubular member 6.Member 6 is pivoted at its inner ends to base 5 at points slightly removed from the ends 8 of the base by any suitable means. In theconstruction illustrated a U-shaped metal strap 11 is secured to each ofthe legs of base 5. A bolt 12 extends through the strap 11 and member 6to hold them pivotally together. A suitable nut is threaded over the endof bolt 12. Similarly, a bolt 13 extends through the strap 11 and base 5to secure them together when the nut of the bolt is tightened intoplace. Member 6 can be pivoted upwardly to the position shown in Figs.

2 and 3 or can lie on top of base 5 when in collapsed position.

In order to secure hammock 1 to the stand, end section 4 in itstransverse tubular position is provided with spaced hooks 14 whichextend through the section and are held in place by suitable nuts. Thehook portion of each hook 14 is disposed inside section 4.

Member 6 on the opposite side of the stand is provided with hooks 15 inits transverse portion and each hook is Fig. 8 is a vertical sectiontaken on line 8-8 of Fig. 1 I

to the end transverse pieces 19 that extend through the ends of thefabric of the hammock. Hooks 18 are aligned with the hooks on the standwith the result that at one end of the hooks 18 are hooked over hooks 14and at the other end over the hooks 15 when the hammock is in assembledposition.

In this position the chain or other like means are hooked to hooks 16 ofmember 6 and the corresponding hooks 17 of base 5. In hooked positionthe hammock 1 tends to pull member 6 to an upright position and thistendency is ofisct by chains 20 tending to pull member 6 toward base 5.

Fig. 2 shows hammock 1 in a slack position with chains 20 extended. Fig.3 illustrates the hammock in taut day-bed-like position with the chainsshortened.

In assembling the hammock stand assembly of the invention the tubes 2and 3 are slipped over the ends of the legs of base 5 and section 4. Thetubes abut straps 11 on base 5' and are limited in movement over tubes 2and 3 by the curvature of the tubes. Member 6 is then raised and hammock1 is hooked to member 6 and section 4. Chains 20 are then hooked to base5 and to member 6 to secure the hammock to the stand in the desiredposition. Disassembly is accomplished in reverse order to assembly andthe parts can then be placed together with the length of the packagebeing governed by the length of base 5 and member 6 which extends frombase 5 when in collapsed position.

The invention provides a hammock stand assembly wherein a shorter standis provided. Experiments have shown that the stand can be shortenedapproximately three feet without effecting stability or requiringshortening of the hammock. This means a stand of less weight can beprovided that is readily packaged for transportation. In addition, thetautness of the hammock is easily adjusted and this permits the hammockto be employed much like a day bed.

Various modes of carrying out the invention may be employed within thescope of the accompanying claims which particularly point out anddistinctly set forth the subject matter regarded as the invention.
